The present invention relates to surface-modified fillers obtained by mixing a filler with water, adding an water-based organosiloxane composition with very thorough mixing, wherein the organosiloxanes are soluble in water and contain, in addition to OH groups, at least one amino-functional group and optionally a functional group from the series consisting of alkyl, haloalkyl, alkenyl, glycidyl ether alkyl, acryloxyalkyl and methacryloxyalkyl, and wherein a functional group is bonded to each silicon atom of the organosiloxane, and drying the mixture. The present invention also provides a process for the surface modification of fillers, their use and ethylene-vinyl acetate copolymer compositions which include the surface-modified fillers.
